Is this an assumption you are making? Or, can you provide specific web
page designers who have said this is what they are doing? 

The pseudo-text was done for your convenience. So you have a little idea
of who I am and my background...
I coded the complex script support for IE 4.01 and IE 5, as well as
enabling other software like Publisher 2000. I have been doing
international text processing for about 20 years, so I understand how
this stuff works...or at least is supposed to work. 8-) I have also been
responsible for shaping scripts and OpenType font support in Windows.

Yes, that would be ideal. But my point is, you can't implement that for
Thai that without breaking existing pages out there. They rely on white
space collapsing to a space, not to nothing.

Collapsible white space disappears at the beginning and end of the line.
See the rules in CSS 2.1 or CSS3 Text.

Also, if you're writing a test for Thai handling, using Latin chars as
pseudo-text isn't going to get you relevant results.
